Hello,
I am attempting to create a program that basically reads in properties from a TDMS file and uses them to generate a digital output signal of a series of pulse trains with delays in between a specific number of pulses and then acquire acquire the same signal and save the signal in a TDMS file.
Anyway, the main thing I am asking about is the frequency of pulses in the pulse train. When I set to the frequency, the TDMS file that is created from my program does not have pulses that match the frequency I have set. I will set the frequency to 2 Hz and the frequency of the pulses will appear to be around 1.3 Hz. I have graphs connected to the wave I am attempting to create before it is passed to the DAQmx Write.vi and it reflects the values I send in, which leads me to believe that the problem either lies in the generation or the acquisition of the signal.
I have included my files with control values already put into place (instead of having properties read in from a separate TDMS file). Is there a problem with how I have anything set up (in the loop or whatnot), or is there something about the generation and acquisition that adds a delay?
Thank you for any help, and let me know if there is any additional information I can give.
